Deploy containers to Azure App Service

In this tutorial, you use Visual Studio Code to create a containerized Node.js application using Docker, push the container image to a registry, and then deploy the image to Azure App Service.

Prerequisites

Install the Docker extension

Install the Azure App Service extension

Azure subscription

If you don't have an Azure subscription, sign up now for a free account with $200 in Azure credits to try out any combination of services.

Sign in to Azure

Once you've installed the Azure extension, sign into your Azure account by navigating to the Azure explorer, select Sign in to Azure, and follow the prompts. (If you have multiple Azure extensions installed, select the one for the area in which you're working, such as App Service, Functions, etc.)

Sign in to Azure through VS Code

After signing in, verify that the email address of your Azure account (or "Signed In") appears in the Status Bar and your subscription(s) appears in the Azure explorer:

VS Code Azure explorer showing subscriptions

Note

If you see the error "Cannot find subscription with name [subscription ID]", this may be because you are behind a proxy and unable to reach the Azure API. Configure HTTP_PROXY and HTTPS_PROXY environment variables with your proxy information in your terminal:

# macOS/Linux
export HTTPS_PROXY=https://username:password@proxy:8080
export HTTP_PROXY=http://username:password@proxy:8080
# Windows
set HTTPS_PROXY=https://username:password@proxy:8080
set HTTP_PROXY=http://username:password@proxy:8080

Verify Docker install

Verify that you have Docker installed properly by running the following command in a terminal or command prompt:

docker --version

The output should appear something like the following:

Docker Version 17.12.0-ce, build c97c6d6
